Pregnancy and birth outcomes of multiple gestations with PPROM occurred within 24 h after fetal reduction: A case series

Abstract

Objective: The study aims to analyze the pregnancy outcomes of multiple gestations with preterm premature rupture of membranes (PPROM) that occurred within 24 h after fetal reduction with potassium chloride (KCL). Materials and methods: We identified and evaluated the outcomes of 16 retrospectively recorded multigestational pregnancies that met the inclusion criteria between 2006 and 2016, from the Obstetrics Department of Shandong Provincial Hospital. A total of 16 patients carrying twins or higher order multiple gestations experienced PPROM within 24 h after fetal reduction, and all of them received expectant management after understanding the relevant risks. The maternal and neonatal records were retrospectively collected and reviewed. Every surviving child was followed up to at least 2 years old. Result: Of the 16 cases, 12 cases (75%) ended in successful pregnancy, resulting in the delivery of at least 1 child surviving from a multiple gestational pregnancy. All cases of successful pregnancies were either term (≥37 weeks) or near-term (36+5 weeks) at delivery. And of those 20 infants delivered, only 3 were low birth weight infants (<2500g) (15%), None of the 16 women had fever, or other clinical symptoms and signs of chorioamnionitis during hospital stay. Postnatal follow-up of the surviving babies showed no obvious sequelae thus far. No newborn baby had neonatal complications, or needed to be transferred to neonatal intensive care unit. Conclusion: Overall, our data demonstrate that dichorionic diamniotic (DCDA) twins or higher-order gestations who experienced PPROM of the reduced fetus within 24 h after selective reduction with KCL had relatively good outcomes with expectant management alone.
